| Abstract | Treatment of Hazardous wastes involves complex sequences and meticulous planning to
ensure adequate and proper achievement of desired objectives of stabilisation, detoxification
and secured disposal. Dedicated industrial treatment can achieve more success in these terms
considering the advantages of consistent waste compositions, minimum transportation risk,
better control and modifications in treatment. However, one significant issue, that is the capital
and operating costs of hazardous waste management makes it an impractical and non-feasible
and mostly undesired option.
Central Hazardous Waste Treatment and Disposal Facility (CHWTDF) has attempted to solve
this precise problem, by using the economies of scale. However, it has simultaneously invited
other problems like optimum technology selection to maximise treatment objectives, planning
and management aspects to economise the operations.
This study attempts to address the issue of appropriate technology selection by studying the
interactions in the waste compositions from certain typical industrial sectors and the rational
selection and sequencing of the technologies to achieve maximum benefit, lower costs, better
material recovery potential and better monitoring control on hazardous waste treatment.
It was found that Analytical Hierarchy Process can be efficiently used to compare technology
alternatives on the basis of various criteria. An in-depth sensitivity analysis can also be
performed to appraise the variations in the technology selection rankings with respect to
changes in the criteria.
An Excel based spreadsheet presents the technology selection with emphasis to waste
segregation, waste generation variance factors and selection of technology options. A case
study has been developed to demonstrate the feasibility of the framework. |
